VALIDATION OF SOFT SENSORS IN MONITORING AMBIENT PARAMETERS

The soft sensor technology is an innovative tool for obtaining measurements in complex experimental conditions. Recently it has been introduced in the field of cultural heritage to solve the problem of a non-invasive ambient monitoring. This work shows from a statistical point of view how well are estimated the physical atmosphere parameters in specific points of the monument by an Elman network. The accuracy of the virtual measures is analysed by means of a two-phase procedure, based on suitable substitution errors.
